We’re excited to announce a new addition to Tonic Health: Dr Gemma Newman, the UK’s ‘Plant Power Doctor’. Dr Gemma will be the Team Tonic GP, joining us on our mission to help people harness the power of their immune system with optimal nutrition, vitamins, minerals and plants.

Based in London, Dr Gemma has over 16 years' experience as a doctor, Senior Partner and NHS family physician. She has worked in many specialities as a doctor, including elderly care, endocrinology, paediatrics, obstetrics and gynaecology, psychiatry, general surgery, urology, vascular surgery, rehabilitation medicine and General Practice.

Dr Gemma knows first hand the importance of diet and lifestyle on human health, including the immune system. A strong advocate of a holistic approach to medicine, she is on a mission to help her patients find their own path to wellness that involves empowerment, autonomy, and plants. She has a specialist interest in holistic health, plant-based nutrition and lifestyle medicine. 


Discovering the power of plants

After seeing over 3,000 patients as a GP, Dr Gemma began to realise that the tidal wave of chronic diseases we’re facing in the western world just wasn’t improving in her patients. Dr Gemma herself had struggled with her health, and sought to explore the power of plants after seeing her husband run a marathon one hour and ten minutes faster than his previous time due to plant-based eating.

She discovered that a whole foods plant-based approach to eating had the benefits of not only faster recovery times for athletes, but also reduced inflammation from oxidative stress. In fact, it had the potential to improve or reverse 14 of the top 15 causes of death in the West. Dr Gemma made it her mission to make this information accessible and available to not just her patients, but to everyone that she reaches. 


Spreading the word

And she reaches thousands. With an online community of over 43,000 people, Dr Gemma has now been featured on Sky News, BBC Radio, ITV, Channel 5, Good Housekeeping and Glamour magazine to name a few – showcasing the powerful transformations that are possible when people embrace a whole food plant-based diet.

Tonic Health is looking forward to working with Dr Gemma on developing our vision for better immune health and education for all. We’ll be bringing you a special blog from Dr Gemma each month on the Tonic Health website, discussing the latest science and the roles plants can play in helping our bodies and immune system function optimally.

In the meantime, follow Dr Gemma at @plantpowerdoctor on Instagram, check out all her free resources at and wish her well on Team Tonic!
